An increasing amount of scientific work is performed in silico, such that the entire process of investigation, from experiment to publication, is performed by computer. Unfortunately, this has made the problem of scientific reproducibility even harder, due to the complexity and imprecision of specifying and recreating the computing environments needed to run a given piece of software. Here, we consider from a high level what techniques and technologies must be put in place to allow for the ac…

The DASPOS project is an NSF-funded collaborative research project designed to explore the technical means of preserving the data and software components necessary to reproduce and build upon published scientific results. This technical report series consists of short reports that outline background, case studies, and technical results related to data preservation, with a focus on high energy physics.
